Carnap Papers
# Carnap Papers

The Rudolf Carnap Papers are a large collection of documents and photographs that record much of the life and career of German philosopher Rudolf Carnap. They are used by scholars and historians not only for research into his life, but also for research into his theories and the theories of other scholars with whom he corresponded. The Carnap papers are restored, maintained, cataloged and housed in the Archives Service Center, University Library System, University of Pittsburgh. They include extensive correspondence, lecture outlines for courses that he taught, and drafts of his published works and unpublished manuscripts. Much of the content of the Rudolf Carnap papers is available electronically and searchable through the archive. His work on metaphysics being essentially a question of semantics is still cited and have been further expanded by other scholars.

His papers document why he is considered a major contributor to the study of metaphysics. He was also a member of the Vienna Circle.
